How To Control the Burner and Find Gas Leaks
The flames on the gas burner should be full and steady, with no sputtering and no trace of yellow. To adjust the flame height on the main burners, call a professional service person. To adjust the height of the pilot flame, turn the flame adjustment screw until the flame is from 11/2 to 2 inches high. The adjustment screw is located near the gas valve on the pilot assembly, if the control has this adjustment feature.
If you suspect leaks around the furnace unit, stir up a mixture of liquid detergent and water. Paint this mixture on the gas supply line along its connections and valves; the soapy water will bubble at any point where there's a leak. If you find a leak, try tightening the leaking connection with a pipe wrench, but be careful not to overtighten the connection. If the pipe connections or valves still leak, call a professional service person.
Now that you know how to fix your gas furnace, you'll be able to stay warm and quite possibly save a few dollars on professional repairs.
